For example, one study identified RSF1 as a reader of histone H2AK119 ubiquitination (H2Aub), which is critical for maintaining a repressive nucleosome architecture at gene promoters. Although MIR6813 is not explicitly mentioned in this work, its placement among regulatory noncoding RNAs suggests that it could function in a similar pathway—perhaps by influencing chromatin remodelers or stabilizing repressed chromatin states—to modulate gene activity. Such a role would be consistent with a broader scheme where noncoding RNAs interface with epigenetic regulators to fine‐tune developmental gene expression and lineage specification."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nIn a complementary approach, another study explored RNA interference strategies against key oncogenic drivers, where the silencing of HBx and c-myc transcripts in hepatocellular carcinoma was achieved through shRNA expression. Although this report does not explicitly investigate MIR6813, the effective downregulation of target genes by RNA interference highlights a paradigm in which endogenous small RNAs could serve analogous tumor‐suppressive functions. If MIR6813 acts as a microRNA that regulates gene expression similarly, it might modulate oncogenic pathways by targeting transcripts involved in cell growth and survival, thereby contributing to therapeutic strategies against hepatocellular carcinoma."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "2"}]}, {"type": "t", "text": "\n"}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Zhuo Zhang, Amanda E Jones, Wei Wu, et al.
